Trimethoprim

Description:
Trimethoprim is an antibiotic primarily used to treat bacterial infections, particularly urinary tract infections. It functions as a dihydrofolate reductase inhibitor, disrupting the bacterial synthesis of folate, which is essential for DNA and RNA production. The chemical formula of trimethoprim is C14H18N4O3, and it has a molecular weight of approximately 290.33 g/mol. This compound is typically a white to off-white crystalline powder that is soluble in water and methanol but has limited solubility in organic solvents like chloroform. Trimethoprim exhibits a moderate to high bioavailability when administered orally and is often combined with sulfamethoxazole to enhance its antibacterial efficacy, as seen in the co-trimoxazole formulation. Its pharmacokinetics include rapid absorption and distribution, with a half-life that allows for once or twice daily dosing. Trimethoprim is generally well-tolerated, though it can cause side effects such as gastrointestinal disturbances and, in rare cases, hematological reactions.
